I guess it just boils down to what your goals are and what you want to accomplish with your time.

As others have said if you are looking to become glad lvl in 5s, I think that ship has sailed for everyone. Kromtor mentioned the politics outside of arena and he is spot on. Kids these days dont mess around, if you even got anywhere even close they would wintrade,snipe and ddos you. Not to mention these days only top 2 or 3 in 5s get glad.
